A family of spray suspensions for aerosol deposition of green ceramic layers that subsequently can be sintered to produce both dense and porous ceramic layers. The suspensions comprise a nonazeotropic solvent mixture, a ceramic powder, a dispersant, and a an organic binder. The invention also includes methods for depositing coatings of these ceramic suspensions on a substrate, either singly or sequentially, to form electrochemically efficient multilayer structures that can be economically co-sintered. The suspensions and deposition approach allow formation of thin layers of varying microstructure and composition in the sintered state. The suspensions and deposition approach are likely to be useful in the fabrication of electrochemical devices.
